Did you contact the BBC and/or POE about copyright of the image Stephen?
POE owners Chris and Sarah can't be expected to read every thread and/or post created. That pleasure is for the moderators such as myself and I think you should have left your comment in place.
Regardless of who it is stealing copyright is a very serious offence and it can turn out to be an expensive moment of madness for the thief. In any case it is something that given the opportunity Chris and Sarah would have acted upon.
You refer to the number of views the thread received Stephen, but you also need to consider that people throughout the world are inquisitive and so will look at and read a post with absolutely no intention of commenting, and besides they do not possess the ability to make a difference. They are when all is said and done quite often just looking at Pictures of England and so whilst they may have an opinion, they don't post a response.
I would be interested to hear what the BBC have to say about the person who stole your image and more to the point what they have done about it? I think they need to offer both you and POE an apology with an explanation for the public and a written warning to the perpetrator.
